Im doing the same thing pretty much and everyones told me that you cant. Im going to get the dsm injectors (350cc) used for about 100 bucks and they fit right in just a little tight. hope that helps a little.

350cc is small; don't get me wrong it works, but still they are small. Depending on your choice of turbo they could be too small. I would recommend 550 as it can serve a wide range of setups. There are several ECUs you can use but for forced induction it requires chipping. I would recommend the P06 as it's readily available and on the cheap side. Tuning software is up to you.
One question you should be asking yourself is why only 5-6 psi? More than likely you will probably net about 165-180whp. Turbo kits costs a lot of time, effort, and money. And while you may correct me if I'm wrong, it sounds like you're trying to cheap out with a completely stock motor. If you don't want to invest 300-475 or so into proper fuel delivery than I doubt you would invest the 800-1250 or so into a reliable bottom end. Stock conditions would make this setup unreliable in the long run. If all you want is those kinds of numbers, I would recommend an H22 or F20B swap instead.'94 JDM H22A: 178whp 146wtq

If you want to run 0-1psi boost then yes you can use the stock injectors.Originally posted by 92cordlx View Post
Any more than that and you need bigger injectors.
lb's of boost doesn't really mean anything either - It's only a pressure rating.
You need to work out how much HP you want to make to get the correct injector size.

350cc is very small. The 450cc "blue top" DSM injectors are about as small as you want to go.
For tuing, you'll want a P06 ECU, chipped and tuned for YOU CAR. If you are not familiar with ECU tuning, save your money and pay someone who is. It is almost 100% guaranteed that you will blow up your motor very quickly with a turbo if you don't tune the ECU properly.

yea im going with a t3/t4 turbo i was told the stock injectors would work that why i was asking.but if i use the dsm ones i would like to run about 8-10lbs with a good tuneComment

The dsm 450cc injectors should work until you get to 230whp or so... Then I would look to go larger. You might be able to do more, but if you end up underfueling under boost, kiss that engine goodbye! It's always good to go a little bigger than you need. Not too much bigger, but leave room for error.

ok i found some black top injectors for $75 im thinking of buying. i have a friend with a p06 ecu he said i can get for $50. i need to know now were do i get the chip to run my carComment

You want the blue top injectors. The black tops are not what you need.
As for the ECU, you don't want a "chip". You should NEVER run your car on a generic chip with turbo (or at all, for that matter, but ESPECIALLY with turbo.) You will need to have your ECU modified and tuned by somone that knows what they are doing... or you need to learn how to do it yourself.
